Abstract

sistema de respiro para tanque de combustível. a invenção refere-se a um sistema de respiro de tanque de combustível (10) para um veículo automotivo compreendendo: - um tanque de combustível (1) compreendendo uma cúpula de vapor, - um tubo de reabastecimento (2), - um purgador de vapor de combustível (3) que é ligado ao tanque de combustível (1) por um conduto de entrada (4), em que o conduto de entrada (4) é ligado ao tanque de combustível (1) através pelo menos de um orifício (5) que é permanentemente aberto, o orifício sendo disposto na cúpula de vapor do tanque de combustível (1) em uma condição estática e - um dispositivo obturador normalmente fechado (cvs) (6) que se comunica com a atmosfera e que é ligado ao purgador de vapor de combustível (3) por um conduto de saída (7), o dispositivo obturador normalmente fechado (6) compreendendo uma válvula eletricamente acionada sendo fechada quando a válvula eletricamente acionada é desenergizada, em que o dispositivo obturador normalmente fechado (6) é configurado para ser aberto durante o processo de reabastecimento do veículo e para ser fechado quando o combustível no tanque de combustível (1) atinge um nível de enchimento predeterminado e quando o veículo está em operação normal.fuel tank breather system. the invention relates to a fuel tank breather system (10) for a motor vehicle comprising: - a fuel tank (1) comprising a vapor dome, - a refueling pipe (2), - a fuel trap fuel vapor (3) which is connected to the fuel tank (1) by an inlet conduit (4), wherein the inlet conduit (4) is connected to the fuel tank (1) through at least one orifice ( 5) which is permanently open, the orifice being disposed in the vapor dome of the fuel tank (1) in a static condition and - a normally closed shutter device (cvs) (6) which communicates with the atmosphere and which is connected to the fuel vapor trap (3) by an outlet conduit (7), the normally closed shutoff device (6) comprising an electrically driven valve being closed when the electrically driven valve is de-energized, wherein the normally closed shutoff device (6) is configured to be opened during the vehicle refueling process and to be closed when the fuel in the fuel tank (1) reaches a predetermined fill level and when the vehicle is in normal operation.
